I kinda guessed that James and Lily might have been the Animagi following Harry, Sirius and Remus back to Grimauld Place... Was I right? One question... Is Lily the other person that was in Professor Hund's living quarters, the woman?

I KNEW IT! The first time we met Professor Hund, I knew he was Sirius using the Polyjuice Potion, but after the Christmas feast, I knew Hund was actually James! I didn't realize about Lily until the very last minute.

about last chapter..."The class immediately stuck their heads into the cauldrons and began to add the boomslang skin." it sounds as if they put their heads INTO the cauldron.just to let you know.great story so far though,i had my suspicions about james and lily.
